lymphoma, non-Hodgkin's

Introduction

lymphoma, non-Hodgkin's, any cancer of the lymphoid tissue (see lymphatic system) in which the Reed-Sternberg cells characteristic of Hodgkin's disease (the other category of lymphoma) are not present. There are about 10 different types of non-Hodgkin's lymphomas, some slower- or faster-growing than others. Non-Hodgkin's lymphoma can affect children as well as adults. In most cases the cause is unknown, but an increased incidence has been observed in people who have been exposed to Agent Orange, and some forms of the disease are frequently seen in people with AIDS, many of these in association with latent Epstein-Barr virus infection.
